    I think it breaks down the cell walls?

    That's kind of what I read on Manky Sankey's website yesterday. Just not sure about the DNA mutation though. May have another look at the website later.

    Just had a quick look at the website and it looks like treatments used to remove blanket weed and green water work by breaking down the cell walls but UVCs work a different way. The way I understand it is a UVC will remove green water but doesn't do much if anything to remove blanket weed as it can only work on what goes through it. What tends to happen is you get green water which your UVC deals with and your filters then catch it but as the algae that makes the water green is consuming some or all of the the Nitrate in the water the blanket weed hasn't got enough to feed on so doesn't grow as quickly if at all but as you start to get rid of the algae that is giving you green water there is more Nitrate for the blanket weed to eat and so it starts to grow more quickly. That's the way I understand it anyway.

    OK I know there are other things that the algae and blanket weed feed on like Ammonia and Phosphate but if your filters are working properly then they should be removing the Ammonia before anything can feed on in. Or at least something along those lines.

    Sunlight has a lot to do with it as well as that's what made me ask the question in the first place as in a garage or shed there would be very little if any sunlight.

    you have hit the nail on the head. sunlight. you read most of the qt builds are indoors. and do not have uv on tanks.so no algi, mine has been running for 3 years now. and not one bit of green. I agree other forces come into the
    equation , don t forget on a grow on we also feed a hell of a lot more then a main pond. because we want to bring them on quicker. most people like to build there main ponds in open sunshine. out in the open and not in the shade.
    that's where the algi problem starts. that's just my opinion

    Can you explain exactly what it does please as I would like to know so I am better informed please?
    you can yes, but you would need a bank of them set up and not a single unit for it to be effective

    OK so if a single UVC wouldn't be very effective at killing off bacteria why do various treatments require you to turn off your UVC for a week or so? I'm not trying to argue with you just would like to know so more about them that's all or is it just that all they do is help to remove green water caused by algae? If so, that's all well and good

    The UV alters the molecular structure of things which is why you turn the uv off, something’s are more susceptible to uv. It’s a bit like infra red, some things burn under the sun more than others.

    i think the issue with bacteria etc is the strength of the UV does and the exposure time. Pass your hand over a uv light is fine, hold it there for a few minutes and you’ll feel it

    What size is that tank, you may have already mentioned it?

    Looks like you'll be done and dusted before I will be with my QT
